Brenda Applegate, executive director of the Beaver County Historical Research and Landmarks Foundation said the region has a head start in marking the trail. The organization through grant funding has established interpretive historic markers in six spots where the expedition stopped between Pittsburgh and the Ohio state line.

She said markers are located in Elizabeth, where a 55-foot keelboat was supposedly built for the trip; Baden, the site of America’s first professional military training ground; Rochester, at the confluence of the Beaver and Ohio rivers; Fort McIntosh, in Beaver; Georgetown; and a spot known as the “Point of Beginning” at the Ohio state line, which was used as a starting point to survey the western United States.
